The attorney for former Chicago Bears quarterback Bob Avellini said he has hired a private investigator to look into details of his client’s blood-alcohol test as Avellini awaits trial on a felony DUI charge.

During a court appearance today, attorney Martin LaScola said the investigator would look into details of the blood draw taken after Avellini’s September arrest, a prosecutor said.

Records show that Avellini, a Bear from 1975 to 1984, had a blood-alcohol level of 0.181 – more than twice the legal limit – four hours after Roselle police stopped him near his home on Sept. 15. He was charged with aggravated DUI

At the time, Avellini, 60, was nine days into a two-year term of probation for a 2012 misdemeanor conviction for drunk driving. Avellini also has a 2002 conviction for DUI, according to court records.

In addition to the felony DUI charge, Avellini is being prosecuted on a charge of violating his probation in the 2012 case. As part of his sentence in that case, his license was suspended.

As a condition of bond, Avellini was ordered to wear an ankle device that can detect the consumption of alcohol and alert authorities.

The monitor had caused a rash on Avellini’s leg, according to files, and the court allowed its removal last month. As an alternative, Judge Daniel Guerin ordered Avellini to undergo regular tests and to submit to surprise testing.

Since his September arrest, Avellini has completed an alcohol treatment program at a Florida facility and is participating in a local program, according to a court motion filed by his attorney. He has made “substantial” progress toward the completion of 300 hours of community service ordered in 2012 sentence, according to the court document.

Avellini and LaScola declined to comment.

If convicted on the felony DUI charge, Avellini faces up to the seven years in prison.

Avellini has faced six DUI-related arrests since 2002 and has beaten DUI charges three times in the past decade, records show.

Chicago Bears receiver Josh Morgan on Tuesday agreed to a deal in which the misdemeanor simple assault charge against him would be dismissed if he meets several conditions, including completion of community service, Washington D.C. court records show.
